Abstract

The embodiment of the invention discloses a method of generating a molecular photoelectric hologram under an elliptic polarization laser action. The method comprises the following steps of a) computing movement conditions of an ionized electron in a laser field so as to obtain speed and a movement locus of the ionized electron; b) obtaining the movement conditions, which include an initial phase, a return moment and a drift time, of a required signal electron on the basis of the movement speed and the movement locus of the ionized electron; c) computing to obtain an ionization phase and the drift time of a reference electron on the basis of the computation of the movement conditions of the ionized electron in the laser field and the movement conditions of the signal electron thereof; d) respectively computing to obtain phase accumulations of movements of the signal electron and the reference electron in the laser field; e) computing to obtain a phase difference so as to make a photoelectric hologram. By adopting the method, through changing a degree of polarization of elliptic laser, a dynamic process of an ionized electron wave packet is influenced, so that generation of the molecular photoelectric hologram is further controlled, thus the molecular photoelectric hologram is precisely made. The method is simple and easy to apply, and has important significance to understanding dynamic behaviors of the electron wave packet in strong field physics and characteristics of the molecular photoelectric hologram.

Description

technical field [0001] The invention relates to the field of strong-field laser physics, in particular to a method for generating molecular photoelectron holography under the action of elliptically polarized laser light. Background technique [0002] "Holography" refers to all information about the light waves emitted by an object: both the amplitude or intensity and the phase. British scientist Dennis Gabor (Dennis Gabor) proposed holography in 1948, and won the Nobel Prize in Physics for this in 1971. His original purpose was to use holography to improve the resolution of electron microscopes. However, initially limited by the light source, it has not been well developed. [0003] The subsequent invention of lasers and the advancement of laser technology promoted the further development of holography. At present, holography mainly uses laser as the light source. The laser beam is divided into two by a beam splitter. One of the beams is irradiated on the object to be phot...
